To @ZZ whom, it may concern: Be it known that I, WALLACE S. AYRES, a citizen of the United States, lresiding at Hazleton, in the county of Luzerne and State of.

' besides accomplishing it in a more economical manner than heretofore, as well as permitting of the construction of a separator-machine which will occupy much less height and floorspace than those now in use. These results are accomplished by providing for carrying out the operation of separating the materials through the influence of two forces, maintaining two principal motions, one of which causes the material under treatment to move forward, while the other acts upon it transversely at any desired angle. In other words, the separation is to be effected by those pieces or particles having but little frictional resistance following one force or motion, while those having a greater frictional resistance follow the other.

More directly, the present application in volves another embodiment of the invention broadly set forth and claimed in acompanion application, Serial No.47,808, filed February 14, 1901. In this companion application are embodied the features generic to all forms of the invention, while the present case presents a rsimple andeftlcient type of machine which effects a separation by utilizing the broad idea of the invention in an economical and practical manner.

With these and other objects in view, which will be readily apparent as the nature of the invention is better understood, the 'same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

The specific type of machine forming the subject-matter of the present application is also necessarily susceptible to a variety of vmodifications. without departingV from. the

spirit or scope ofthe invention; but the pre-- ferred form of themachine is shown in the ac.`

com panying drawings, in which- F-igure l is a plan view of a separating-machine constructed in accordance with the prese ent invention. tional view thereof, showing the forward inclination of the separating-:Hoor to provide forv maintaining the forward motion of the stream Fig. 2 is a longitudinal sec-A of material by gravity. Fig. 8 is a transverse v sectional view on the line 3 3 of Fig.2, showing more plainly the transverse inclination of the floor with reference to the guide to maintain the line of movement of the main stream. of material against or along with said guide.

Fig. 4 is a plan view of another form of machine in which a single revoluble disk constitutes the separating-floor. Fig. 5 1s a trans-` verse sectional view on the line 5 5 of Fig. 4.

Like numerals of reference designate corresponding parts in the several gures of the drawings.

As-set forth in the other application afore said, the present invention involves as funda-2 mental thereto a separating-floor which is inclined transversely tothe line of movement of the stream of material and, in a more restricted aspect, a separating-floor which is inclined in two directions to insure a complete carrying forward of all particles or substanceshaving a less angle of repose-than the trans` verse kinclination of the floor.v

In `embodyingthe above-recited features in the form of machine shown in Figs. 1 to 3 l the separating-floor (designated in its entirety by the numeral Dist-made up of a series of overlapping revoluble disks 2, preferably provided with fl-at or conical surfaces, which may be smooth,froughened, or otherwise formed to permit of certain particles or substances freely passing thereover, while others are. frictionally engaged by the surfaces ofthe disks and are moved out laterallyl from the main stream of material, which traverses the entire Hoorn-ina* forward or longitudinal direction. It is unimportant to the successful carrying out of the-invention precisely how the revoluble disks Qfhare constructed or mounted; but for illustrative purposes each of the dis-ks 2 is shown as provided with a central journal 3, mounted in a suitable fixed bearing 4, fitted to'fa supportingfframe 5, which supporting-frame may be horizontal or inmay be utilized to impart a synchronous movement to the individual separating or conveying disks 2; but a simple means for accomplishing this result is shown in the drawings and resides in providingthe peripheral edges of the disks with worm-teeth 6, engaged by the worms7 and 8, carried, respectively,` by the shafts 9 and 10, disposed longitudinally of the supporting-frame and arranged at opposite sides of the longitudinal plane of the separating-lo'or 1. The oppositely-located worms insure a steady and even movement of the individual disks 2, although it will be understood that any gearing or turning mechanism may be employed in connection with said disks to insure the necessary synchronous and steady movement thereof.

The bearings or su pports for the individual disks 2 are preferably longitudinally alined, so that there will be a succession of these disks, one in advance of the other, and in overlapping relation, so as to provide a substantially continuous Hoor over which the main stream of material may freely travel, while slate and other foreign substances will frictionally engage with the surfaces 'of the individual disks and be moved laterally thereby out of the path of the main stream 'of material.

In connection with the form ofmachine illustrated there is associated with the separating-door 1 a guide 11, extending longitudinally of the floor and preferably arranged obliquely across the same to provide a guideway in which the main stream of material is positively held and guided `from its entrance through the feed-spout 12 at the upper end of the fioor to its delivery into the discharge chute or trough 13 at the lower end of the iioor to receive the coal, which has maintained its travel across the ventire floor. The slate and other substances which are worked `out laterally from the main stream of material by the rotatable individual disks 2 are dropped over the edge thereof into the longitudinallyarranged discharge-trough 14, which extends longitudinally of the supporting-frame and serves to receive and carry off the separations from the grades of coal following the line of movement of the main stream along the guide 11- It is to be observed that in the form ofimachin'e shown in Figs. 1 to 3 of the drawings the complete separating-floor 1, made up of the overlapping revoluble 'disks 2, is not only inclined in a forward direction, but also transversely toward the guide 11, thus involving the same combination, in a broad sense, as disclosed in the companion application aforesaid. It should also be noted, however, in the present invention that the angle of inclination in the trough formed by the guide 11 and the surfaces of the disks 2 is a trifle less than the angle of repose of the pieces or particles having the greater frictional resistance, but at the same time a little greater than the angle of repose of those having the least frictional resistance, thus insuring a positive feed of the coal and other good material against and along the guide and the lateral movement or separation of the slate and other foreign substances therefrom. The general transverse inclination of the individual disks toward the guide 11 is designed to be adjusted in any suitable manner and is necessarily sufficiently less than the angle of repose of the pieces or particles having the greater frictional resistance so that such pieces or particles will adhere to the surfaces of therevolving disks and be carried sidewise out of the stream of moving material. This inclination of the disks, however, must at the same time be slightly greater than the angle of repose of the pieces or particles having the least frictional resistance, so that such pieces or particles will always travel along the guide. With reference to this guide it may be stated, as inthe other case aforesaid, that the same maybe straight, curved, or lbroken and set at any angle of Obliquity with reference to the longitudinal plane of the separating-table over which it is placed.

While in the form of machine described the separating-floor is illustrated as being.

IOO

made up of a series of overlapping revoluble disks, it will be obvious that the invention could be carried out by the employment of a single revoluble disk 2, as shown in Figs. 4 and 5 of the drawings. This disk is, of course, to be of a suiicient size to permit of the separating action being accomplished and is not only inclined in a forward direction, but also laterally or transversely with reference to the guide 11a. In connection with the form of machine involving the single disk 2n there is preferably associated a feed-spout 20, arranged to direct the material against the upper end portion of the guide 11, 'While contiguous to the lower end of this guide are arranged the discharge-chutes 21 and 2.2. These discharge-chutes are disposed side by side, and in front of the mouth'or entrance to one of the chutes-namely, the chute 22 for impure coal-there is preferably located a regulating-shutter 23, this combination and arrangement `of parts being substantially `the same as disclosed in my companion applicati'on aforesaid. l

Various modifications of the motions herein IIO construction may be resorted to without de-v parting from the principle or sacrificing any of the advantages of this inventlon.
